ing, presses, and has for one object to provide in combination with the feeder, a con denser cooperable with the feeder, and novel means for timely operating the condenser whereby the hay will be condensed just prior to the delivery of the hay' or other material into the baling; chamber or boX, and whereby the hay will be properly held in position and delivered into the baling chamber to best advantage.

Another object of this inventiomis to provide novel means for actuating the feeder.

The invention also comprehends the pros vision of a baling press wherein the spacing or head block may be dropped into the hopper at the proper time, and then automatically or mechanically placed in position, so as to'relieve the operator of the duty of placing the spacing block into the baling chamber by hand, which is objectionable for well known and obvious reasons.

It is also ithin the scope of the invention to provide the improved features above noted, which may be readily applied to prevailing types of baling presses, and which will be comparatively inexpensive in manufacture and application, aswell as being thoroughly practical, serviceable and efiicient.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawings, wherein r Figure 1 is a plan view of the improved baling press, a portion of the plunger rod or pitman being broken away. Fig. 2 is an enlarged sideele'vation of the baling or compression chamber and accompanying parts,

illustrating the feeder at the end of its downward stroke. Fig. 3 is an enlarged side elevation, taken from the opposite direction, with the parts in the sameposition. Fig. 4: is an enlarged longitudinal section or the parts illustrated in Figs. 2 and 3, the section beingtaken approximately on the line 4+4 of Fig. 7, and the feeder beingillustrated in.

its raised or idle position. Fig. 5 is, an enlarged sectional view taken on the line 55 of Fig. 7;, and ill-ustratingthe feeder started into the hopper, and the condenser moved to cooperable position with the feeder. Fig. 6 1s a view similar to Fig. 5, illustrating the feeder in depressed position and in the act of placing the spacing or head block in posi tion within the baling chamber. Fig. 7 is an enlarged front end view of the baling chamber and accompanying parts with the feeder 1Il raised position. Fig. 8 is a cross section taken on the line 8+8 of Fig. 2. Fig. 9 is an enlarged detail iew of the actuating means ifor the condenser, parts being shown in sec The baling press embodies the usual baling or compression chamber or box 1, having the upper hopper 2 for receiving the hay and conducting it into the. compression chamber, the sides of thecompression chamber 1 being provided with the usual dogs 3 for holding the hay compressed in rear of the hopper 2. A plunger head 4 is mounted for, reciprocatory movement Within the baling chamber 1 below the hopper 2, and is provided with an upper rearwardly projecting shutter 5 for closing the discharge opening of the hopper 2 or the entrance opening of the chamber 1, when the plunger 4 is moved forwardly. A casting 6 is secured to the rear side of the plunger head 4: and has engaged therein, the forward end of the plunger rod or pitman 7 which connects the plunger head l with the horse power actuating machanism 8 to enable the plunger head to be reciprocated properly, although it is to be understood that any suitable means maybe em ployed for actuating the plunger head with out in any way altering the operation of the present mechanism The feeder embodies a casting 9 secured upon a lateral rock shaft 10 j ournaled to the frame of the press above the forward end of the chamber 1 and in rear of the hopper 2, a pair of'curved bars or arms 11 being secured to the casting 9 in any'suitable manner and having their free ends overhanging the hopper 2 and projecting rearwardly.

- The arms 11 are-adapted to work within the slots 12 of the rear end of the hopper-2, when the feeder is oscillated. A plate 13 having a serrated edge is secured to the free ends of the arms 11, to constitute a jaw for the feeder, and a pair of bars 14 are secured to the arms 11 adjacent the aw 13, and have secured to their free ends, a supplemental or secondary jaw 15' which is normally disposed adjacent the upper portion of the rearend of the hopper 2 when the feeder is raised, while the'jaw 13 is disposed sufficiently above the hopper 2, to enable the operator to feed the hay into the hopper.

The actuating mechanism for the feeder, and which is connected to the plunger head 4, embodies a pair of levers 16 having their upper ends fulcrumed, as at 17, to the casting 9, a pair of links 18 being pivoted to the lower ends of the levers 16, and projecting forwardly toward the plunger head-4. pin 19 is carried by the forward or free ends of the links 18, and workswithin the slots 20 of a pair of inclined bars or guides 21 carried by the plunger head. The forward or upper ends of the guides 21 are secured'to the casting 6 of the plunger head, while the lower or rear ends of the guides '21 are secured to a hanger 22 carried by the rear end of the shutteror closure plate 5. A' stem 24 threadedly and adj-ustably engages the casting 9 between the levers 16 adjacent their fulcrum 17, a bearing plate 23 being slidable upon the stem 24 and seating against the rear edges of the levers 16 and there'being an expansion spring 25 upon the said stem 24 and contacting with the bearing plate 23 to yieldably swing the levers 16 rearwardly. In order to swing the feeder upward when the same is free, a segment 26 is secured to one end of the rock shaft 10, and has a chain or other flexible element 27 engaged therea over and attached at one end thereto, and a coiled wire retractile spring 28 is connected to the other end of the chain 27 and corresponding side of the baling chamber 1. The spring 28 thus exerts a tension tending to unwind the chain 27 from the segment 26, to swing the feeder upwardly; A roller 29 is journaled in any suitable mannerto the rear end of the shutter 5, to contact with the front edges of the levers 16, when the plunger head is moved rearwardly, to thereby depress the feeder.

The front end of the hopper 2is open and has disposed therein, between thesides of he hopper, a harp-shaped condenserBO having its lower end secured 1 to a transverse rock shaft 31 ournaled through the sides of the hopper 2 at the front end of the opening between the hopper and baling chamber. The condenser 30 is thus adapted to oscillate between the sides of the hopper to and from the feeder. A cross bar 31 is engaged through the sides of the hopper adjacent the upper edges'and forward ends of the saidsides, for supporting the condenser 30 when it is swung forwardly to normal or idle position. Thus, when the condenser 30 is swung forwardly, it will serve as the front end of the hopper, to receive the hay thereon in the usual manner.

The actuating means for the condenser 30, embodies an oscillatory ratchet wheel 32 secured upon one end of the rock shaft 31 of the condenser, and having the side flanges 33, and the diametrically opposite shoulders 34 and 35 facing forwardly, or in opposite directions relative to the circumference of the ratchet wheel. A lower link 36 engages the oscillatory ratchet wheel 32 between the flanges 33 and adjacent the lower shoulder 34, while an upper link 37 engages the upper portion of the ratchet wheel between the flanges 33 and adjacent the upper shoulder 35, the rear end of the link 36 being upturned and pivoted, as at 38, to the link 37 in advance of the ratchet wheel. A retractile spring 39 connects the front or free ends of thelinks 36 and 37,- to pull the links toward one another, and cause them to yield ably engage the periphery of the ratchet wheel. The rear end of the upper link 37 is connected to a crank arm 40 secured to that end of the rock-shaft 10 opposite the segment 26, whereby the oscillation of the shaft 10 will impart a reciprocatory movement to the links 36 and 37. The links 36 and 37 are providedwith the respective rearwardly facing shoulders 41 and 42 cotiperable with the shoulders 34 and 35, respectively, of the ratchet wheel 32. Theshoulder 41 of the lower link 36 is spaced forwardly from the shoulders 42 of-the upper link for properly oscillating the ratchet wheel 32 and condenser 30 connected thereto.

A pair of stops or lugs 43 are engaged through and project inwardly from the sides of the baling chamber 1, adjacent the rear end of the opening between the baling chamber and hopper, and in the longitudinal lines of the upper dogs 3. The side edges of the'plunger head 4 are provided with notches or recesses 44 to enable the plunger head to move past the dogs 3 and stops or lugs 43 without interference.

In order to limit the oscillation of'the condenser 30, a collar 45 is engaged upon that end of the rock shaft 31 opposite the ratchet wheel 32, and a set screw 46 is engaged through the collar 45 and bears against theshaf-t 31 to hold the collar in place. The set screw 46 provides anupwardly projecting finger, Whichisengage able with; astop 48 secured to thefrespective side of the hopper. denser 30 is swung upwardly "and rearwardly, the setscrew or finger 46 is engage Thus, when the conable with the stop 48, to limit the rearward movement of the condenser, and when the condenser is swung forwardly. andgdownwardly, it is engageable with the cross rod:

31*- to limit the forward movement of the condenser. i

In operation, assuming that the plunger head 4 is moved tothe end of its, forward stroke,-as seen in Fig. ,4, the shutter 5 will movebelow the hopper 2 to close theopeni-ng between the hopper and condensing chamber, and, the feederfwill be returned to raised or idle position under the influence of the spring 28. The operator may thenpitch the hay into the hopper '2 under the feeder I and onto the condenser 30 and shutter 5of the plunger head, it being noted that as the plunger head 4 starts to move rearwardly, the feeder will remainidle duringa portion of the rearward stroke of the plunger head,

to enable the operator to readily place the desired amount of hay into the hopper be fore the feeder'is depressed.- Then, after. the plunger head 4 has started rearwardly and finished part of its stroke, the bearing roller 29 carried by the rear end of theshutter 5 of the plunger head, .will contact with the levers 16, as seen in Fig. .5, and will swing the levers 16 rearwardly" to thereby start the'downward movement of the feeder intothe hopper as seen in ,the'saidfigure' It is to be noted that the spring permits of a yieldable action between the levers 16 and arms 11 to avoid any sudden operation of the feeder, and to enable the feeder to yield relative to the levers 1.6 infeeding the hay into the condensing chamber. Whenthe levers 16 are swung tov move the feeder downwardly, the rock shaft 10.0f the feeder will be oscillated, which will move the crank arm 40 of the said shaft 10 rearwardly, and as a result, the links 36 and 37 will be drawn rearwardly. Ordinarily, when the condenser is swung forwardly, asseen in Fig. 4, the shoulders 41 and 42 of the, links 36 and 37 will be disposed'in front of the shoulders v34 and-35 respectively, of the:

ratchet wheel 32, with the shoulder 42 ofthe upper link 37 in engagement :withzthe shoulder 35 of the ratchetswheeh as seen in Fig. 9. Then, as the links 36 .and 37 are drawn rearwardly, as above indicated, the upper lmk 37 will cause the ratchet wheel 32 to rotate counter-clockwise, as seen inFlg.

9, to swing the condenser 30 upwardly and" rearwardly to the position'illustrated in Fig. 5. The condenser 30 is thus swung into cooperative relation with the feeder, immedi-i' ately after the feeder has started to move,

and just before the feeder jaws13 and 1-5 engage the hay for forcing the same into the condensing chamber.

ward the rear end of the hopper 2, directly under the jaws 13 and 15 of the feeder, and

Thus, the, condenser 3O condenses the hay by forcing it to-[ in this manner, the'hay is not only .condensed prior to the downward movement of the hay by the feeder, but the hay will be directed into thecondensing chamberto better advantage.- Thus, as the plunger head 4 moves rearwardly, the feeder is depressed through the hopper-2 and into thecondensing chamber 1 todeliverfhehay into'the condensing chamber in front of the plunger head. As-the plunger head 4 completes-its rearward stroke, theshoulder42 .of the up per link 37 of the condenser actuating means given a quick initial InOVQlIlGIltiLIld will then 7 gradually lessen in velocity as the hay is engaged and forced downwardly into the baling h ber 1. It is also to be noted that the spring 39 connects the free ends of the links 36 and-.37 to cause the shoulders of the said linkszto snap intoengagement with the shoulders of the ratchet wheel 32 to the ends above noted, I r "After the plunger head 4 has been moved rearwardly, and the hay fed into the baling chamber 1, theplungerrod or pitman 7' is moved forwardly forcompressing the hay withinthe baling chamber 1 and moving the hay forwardly beyond the dogs3. As soon.

as the plungerhead ,4 starts forwardly, the

bearing roller 29 is drawn out of contact with the levers '16 of the feeder, and the feeder will be drawn upwardly under the influence. of thereturning spring'28, it being. noted that the pin 19 of the links 18 connected to; the levers 16 may readily move rearwardly within the slots 20 of theguides 2 1,to enable the feeder to quickly return to raised or idle position. As the feeder is returned to raised position, the links- 36 and 37 willibe moved forwardly toinitial position by. the forward movement of the crank arm 40,'it-being noted that the condenser 30 is returnedto initial position :prior to the completedownward movement of the feeder, and thatthe condenser will thus remain idle while the feeder isbeing raised. The links 36 and 37 moving forwardly will'cause the shoulders 41 and 42-of the links to snap idly past the shoulders of the ratchet wheel-32 f without operating the condenser. The links 18 having thepin 19 slidably engaging the guides 21 permit the levers 16 to have a lim ited movement relative to the plunger head,

v feeder moving downwardly, upon the front being moved forwardly will cause the front ends of the slots 20 to engage the pin 19,

whereby the links 18 will be drawn forwardly for forciblyraising the feeder.

In the foregoing manner,as the plunger head' l is reciprocated, the-feeder and condenser will be operated timely to the ends noted. f

Another salient" or cardinal feature of the present invention residesin the fact that the spacing or head block 49 may be automatically introduced into the'baling chamber 1, after the spacing block is dropped into the hopper 2. Thus, as illustrated in Fig. 4, when the plunger head 4: is at the end of its forward stroke, the spacing block 4:9;may be dropped into the hopper 2 upon the shutter 5 of the plunger head." Then, as the plunger head is moved rearwardly, the shutter 5 will be drawn forwardly from under the spacing block 49, and the forward jaw 13' of the end of the spacing block 49, will cause the spacing block to be tilted downwardly in front ofthe' plunger head, as suggested in Fig. 6. The spacing block -19 may thus be kicked properly into the'balingchamber 1 in front of the stops orlugs 43, which hold the spacing block in place until the plunger head moves forwardly to carry the spacing block with it for dividing the'bales. iAs'suggested in Fig. 6, when the spacing block 19 is not completely depressed into the baling chamber 1 by the. upper jaw 13, the supplemental orrear j aw 15 of the feeder will force the spacing block lengthwise into proper position. With the present mechanism, there fore, it is only necessary for the operator to drop the spacing block 49 into the hopper and onto the shutter 5 of the plunger head, so as to avoid the necessity of the operator placing the spacing block manually into the baling chamber, and rendering him liable to injury.
